(01.164-98) I The present invention relates to an article ofprinters furniture which may be installed, one or more, on a part of aprinting press that carries the impression sheet, for examplesuchas the5 platen ofa job printing press, togsir'nultaneously print and punch, orto enable the use of'such'a press as a punching machine, which mayreadily I be accomplished, simply by omitting theprinting l0 manner.

' oftentimes job printing shops or small printingshops are required toturnout punched werk. Many of such shops are not equipped with punchingmachinery, hence have to efiect the punching Then, too, such shops oftenhave orders for loose leaf work, requiring printing and punching; ofmany sheets of paper.-' Such shops not properly equipped. i'or punching'areat disadvantages in turning out such work,-thusadding to the cost of"production of such class of printed and punched matter. I q j I Thepresent invention has to do with a simple punch device which may bereadily att'ached,*one V V of slightly different-form. r I

' e press 'srovid'ed withaiplaten B and 'ajbedC, the latter fof'supporting the'usual type form in this class of press.

- As 'is'customary, a tympan draw sheet I is secured to theplaten B bymeans of a bail 2 40 which is pivoted to the platenin the usual manner.

'In the main, the punch device of thepresent invention, includes astructure having a plurality of leaves; preferably three, the lowermostof which is herein termed the base leaf, the uppermost of which istermed the cutter leaf, and the intermediate leafis termed the stripperleaf. The punch illustrated in Figure", 10 has a base leaf'3 with adownwardly turnedheell atfits50 rear end, for engaging between theplaten B' and 7 the bail 2 for {positioning this formoi punch device onthe platen; The cutter leaf 5 is of spring metal and it, together withthe *intermediate or stripper leaf'i is secured to the base cutter leaf5 is provided with an opening I!) which j conforms to the shape and'sizepf the cutter. head 8 for cooperating therewith for punchingpurposes. The intermediate or stripper leaf 6 is preferably bowed sothat normally a portion thereof lies even with or slightly above thecutter head 8 to enable ready insertion of an impression sheet in thepunch device. Furthermore the bow-. 7

ing of the stripper leaf enables flexing thereof during the'punchingoperation asthe flatteningof the stripper leaf during the punchingoperation enables it to-spring back to normalposition after the punchingoperation, and thus strip. or

free the sheet from about the cutterhead, so that the sheet may bereadily withdrawn. I

The punch device illustrated in Figures 5 and is constructed quitesimilarly. to that just de- 1 scribed, except that the cutt r leaf I ihas portions of its side eliminated, "for increasing the spring effectof the cutter leaf during punching operations.- Also, the base leafisprovided with lateral lugs 12 which maybe bent about adjacent portionsof the cutter and stripper leaves at the-rear end of the device, for anaid inholding together the leaves, in additior to spotwelding, The punchdevices just described-that is those illustrated in Figures 5, 6, 7,8, 9and 10,; are applied to theplatenB of the press, by inserting the heelor downturned flange 4 between the platen B and the bail 2, asillustrated in Figures 8 and 9, that islpositioning the punch devicesadjacent the lowermargin of the platen. I

One, or several, of such devices" maybe readily applied to the platen asthe punching job requires. Sometimes it so happens that the impressionsheet or other; sheet must be punched in other positions than readilyaccessible by thepunch devices secured bythebail to theplaten; ';I norder to provide such punch devices, theforms illust t in u e 2, and5cnv n n The punch device,of .-Figure 2 includes a base leaf l3,a;stripper leaf l4 and a cutter-leaf 15. The e ea l3 ca rie he c ite e dfiw il the stripper leaf is provided with a' suitable aperture tosurround this cutterhead, and thecutter leaf is provided with anaperture17 to cooperate with thecutter head,as. heretofore described. The leavesare secured together adjacent the rear end thereof .as byspot welding.For attachment of this formof punch deviceto the platen, or to thetympan, l8, the base leaf l3 may be extended to receive abolt, l9havinga flat head 20 which-may be positioned underneath the tympandrawsheet l8, bearing against the underside thereof, with the bolt.passing through a suitable hole inthe draw sheet and through an apertureinthe base leaf l3'of the device. A

nut, 2| is provided to clamp the punch device to the drawsheet indesired position- The base leaf I3, is furthermore provided with tangs22 which are pointed'and enter the draw sheet I8 to position the toe endof the punch device and retain it in fixed positionduring punching- Thepunch device illustrated inFigures 3and 4 yice on the platen.

a cutter leaf apertured at 21 to cooperate with the cutter head 26.These leaves are secured together at their rear ends as by spot welding.Adjacent the rear end of the base leaf 23, pins 28 are secured forentering the tympan drawsheet I8 for positioning the rear end of thepunch device, while adjacent the toe end of the device are tangs 29 forentering the drawsheet to position the toe end of the punch device.

Itwill beobserved that the punch. device of Figures 3 and 4 may bereadily applied anywhere on the surface of the platen simply byinserting the pins through the drawsheet and forcing the tangs 29 intothe drawsheet.

The. several leaves of the punch devices are preferably. of. springmetal with the stripper leaf bowed and with the cutter leaf bent so thatits free end may lie normally away from the cutter head of the punchdevice, to allow insertion of an' impression. sheet and also after thepunching operation to spring away from. thecutter-head for withdrawal ofthe punched sheet.

. As an aid in the operation of they punch device, impression pads may,be fl plied'to the cutter leaf. Figure 7 illustrates apad 30 of U-shapein plan, which is of rubber or other elastic material. This pad isapplied to the outer surface of the cutter leaf 5 surrounding theaperture -10 therein, with the legs directed towardsthe rear end of thedevice, to guide the punching's toward thelower end of the platenwherebythesemay fall from the platen after punching operations. H 1

The form of impression pad illustrated in Figures 5, 6, 8 and 9 consistsof two separatedpads 3| and 32 of rubber or other suitable elasticmaterial, retained on thecutter leaf bymeans of clips 33 securelyfastened to such leaf. The disposition of the two pads 3| and 32 enablestheuse of these as guides to prevent lateral disposition of thepunchings astheplaten is swung from impression position ,to openpositionfor receiving another impression sheet. 5 f
